this looks for me like the CONFIG_ENV_OFFSET+CONFIG_ENV_SIZE is overlapping
uboots code
can you post these values and position of uboot and its size for your device?
$ ls -l u-boot-sunxi-with-spl.bin
-rw-r--r-- 1 xy xy 479836 Apr 9 17:55 u-boot-sunxi-with-spl.bin
I used the following to write u-boot to the SD card (/dev/sdb):
# dd if=/dev/zero of=/dev/sdb bs=1k count=1023 seek=1
# dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
If you need more data let me know pls.
which env-storage do you use (EMV_IN_MMC or ENV_FAT)?
I looked up in the .config file:
# U-Boot 2019.04-rc4 Configuration
$ grep CONFIG_ENV_OFFSET .config
CONFIG_ENV_OFFSET=0x88000
$ grep CONFIG_ENV_SIZE .config
CONFIG_ENV_SIZE=0x20000
$ grep EMV_IN_MMC .config
Maybe EMV_ is a typo and should rather be ENV_ ?
$ grep -i EMV_ .config
$ grep -i ENV_ .config
CONFIG_ENV_SIZE=0x20000
CONFIG_ENV_OFFSET=0x88000
CONFIG_ENV_VARS_UBOOT_CONFIG=y
# CONFIG_SYS_CONSOLE_ENV_OVERWRITE is not set

$ grep ENV_FAT .config
CONFIG_ENV_FAT_INTERFACE="mmc"

CONFIG_ENV_FAT_FILE="uboot.env"
I guess the uboot.env is a hidden file, but occassionally (esp. after
saveenv & reboot) I see this file as a normal file in /, not hidden.
I used "Lamobo_R1_defconfig" as basis and made just a few
irrelevant minor changes in make menuconfig.
It's actually a Banana Pi R1 board.
CONFIG_DEFAULT_DEVICE_TREE="sun7i-a20-lamobo-r1"

It seems u-boot has overwritten parts of itself on the storage medium (uSD
with FAT boot partition).
